In addition, the surface of the sixth lens may be equipped with a greater light path regulating ability, thus enhancing the image quality.

The arc length of any surface of a single lens within the maximum effective half diameter affects the surface's ability to correct the aberration and the optical path differences between each of the fields of view. The longer the arc length is, the better the ability to correct the aberration will be. However, difficulties may be found in the manufacturing process. Therefore, it is necessary to control the arc length of any surface of a single lens within the maximum effective half diameter, especially the ratio (ARS/TP) between the arc length (ARS) of the surface within the maximum effective half diameter and the thickness (TP) of the lens to which the surface belongs on the optical axis.

The ratio between the two is ARS11/TP1. ARS12 denotes the arc length of the maximum effective half diameter of the image side surface of the first lens. The ratio between ARS12 and TP1 is ARS12/TP1. ARS21 denotes the arc length of the maximum effective half diameter of the object side surface of the second lens. TP2 denotes the thickness of the second lens on the optical axis. The ratio between the two is ARS21/TP2. ARS22 denotes the arc length of the maximum effective half diameter of the image side surface of the second lens. The ratio between ARS22 and TP2 is ARS12/TP2. The ratio between the arc length of the maximum effective half diameter of any surface of the rest lenses in the optical image capturing module and the thickness (TP) of the lens to which the surface belongs on the optical axis may be deducted on this basis.

The arc length of any surface of a single lens within the height of half the entrance pupil diameter (HEP) particularly affects the surface's ability to correct the aberration and the optical path differences between each of the fields of view at the shared area. The longer the arc length is, the better the ability to correct the aberration will be. However, difficulties may be found in the manufacturing process. Therefore, it is necessary to control the arc length of any surface of a single lens within the height of half the entrance pupil diameter (HEP), especially the ratio (ARE/TP) between the arc length (ARE) of the surface within the height of the half the entrance pupil diameter (HEP) and the thickness (TP) of the lens to which the surface belongs on the optical axis. For instance, ARE11 denotes the arc length of the height of the half the entrance pupil diameter (HEP) of the object side surface of the first lens. TP1 denotes the thickness of the first lens on the optical axis. The ratio between the two is ARE11/TP1. ARE12 denotes the arc length of the height of the half the entrance pupil diameter (HEP) of the image side surface of the first lens. The ratio between ARE12 and TP1 is ARE12/TP1. ARE21 denotes the arc length of the height of the half the entrance pupil diameter (HEP) of the object side surface of the second lens. TP2 denotes the thickness of the second lens on the optical axis. The ratio between the two is ARE21/TP2. ARE22 denotes the arc length of the height of the half the entrance pupil diameter (HEP) of the image side surface of the second lens. The ratio between ARE22 and TP2 is ARE22/TP2. The ratio between the are length of the height of the half the entrance pupil diameter (HEP) of any surface of the rest lenses in the optical image capturing module and the thickness (TP) of the lens to which the surface belongs on the optical axis may be deducted on this basis.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

To facilitate the review of the technique features, contents, advantages, and achievable effects of the present invention, the embodiments together with the attached drawings are described below in detail. However, the drawings are used for the purpose of indicating and supporting the specification, which may not depict the real proportion of elements and precise configuration in the implementation of the present invention. Therefore, the depicted proportion and configuration of the attached drawings should not be interpreted to limit the scope of implementation of the present invention.

The embodiment of the optical image capturing module and the method thereof in the present invention are explained with reference to the related figures. For ease of understanding, the same elements in the following embodiment are explained in accordance with the same symbols.

As shown in FIG. 1 to FIG. 4, FIG. 7, and FIG. 8 to FIG. 11, the optical image capturing module in the present invention may include a circuit assembly 100 and a lens assembly 200. The lens assembly 100 includes a circuit substrate 120, a plurality of image sensor elements 140, a plurality of signal transmission elements 160, and a multi-lens frame 180. The lens assembly 200 may include a plurality of lens bases 220 and a plurality of fixed-focus lens assemblies 230.

Specifically, the circuit substrate 120 may include a plurality of circuit contacts 122. Each of the image sensor elements 140 may include a first surface 142 and a second surface 144. As shown in FIG. 3, LS is a maximum value of a minimum side length of an outer periphery of the image sensor elements 140 perpendicular to the optical axis on the surface. The first surface 142 may be connected to the circuit substrate 120. The second surface 144 may have a sensing surface 1441. The plurality of signal transmission elements 160 may be electrically connected between the plurality of circuit contacts 122 on the circuit substrate 120 and each of the plurality of image contacts 140 of each of the image sensor elements 146. In an embodiment, the signal transmission elements 160 may be made from the material selected from gold wires, flexible circuit boards, spring needles, solder balls, bumps, or the combination thereof.

In addition, the multi-lens frame 180 may be manufactured integrally, in a molding approach for instance, be covered on the circuit substrate 120 and the image sensor elements 140. A part of the plurality of signal transmission elements 160 may be embedded in the multi-lens frame 180, whereas the other part of the signal transmission elements 160 may be surrounded by the multi-lens frame 180. The positions corresponding to the sensing surface 1441 of the plurality of image sensor elements 140 may have a plurality of light channels 182. Therefore, embedding a part of the signal transmission elements 160 in the multi-lens frame 180 may prevent the signal transmission elements 160 from being deformed in the manufacturing process. Such a situation may cause many problems like short circuits. Thus, the overall size of the optical module may be minimized.

The plurality of lens bases 220 may be made of opaque material and have an accommodating hole 2201 passing through two ends of the lens bases 220 so that the lens bases 220 become hollow, and the lens bases 220 may be disposed on the multi-lens frame 180 so that the accommodating hole 2201 is connected to the light channel 182. In addition, in an embodiment, the reflectance of the multi-lens frame 180 is less than 5% in a light wavelength range of 435-660 nm. Therefore, the effect of the stray light caused by reflection or other factors on the image sensor elements 140 may be prevented after light enters the light channel 182.

Furthermore, in an embodiment, materials of the multi-lens frame include any one of metal, conducting material, and alloy, or any combination thereof, thus increasing the heat dissipation efficiency or decreasing static electricity. This allows the image sensor elements 140 and the fixed-focus lens assembly 230 to function more efficiently.

Furthermore, in an embodiment, materials of the multi-lens frame 180 include any one of thermoplastic resin, plastic used for industries, or any combination thereof, thus having the advantages of easy processing and light weight. This allows the image sensor elements 140 and the fixed-focus lens assembly 230 to function more efficiently.

In an embodiment, as shown in FIG. 2, the multi-lens frame 180 may include a plurality of camera lens holders 181 having the light channel 182 and a central axis. The distance between the central axes of adjacent camera lens holders is a value between 2 mm and 200 mm. Therefore, the distance between the camera lens holders 181 may be adjusted within this range.

In an embodiment, as shown in FIG. 12 to FIG. 16, the multi-lens frame 180 may be manufactured in a molding approach. In this approach, the mold may be divided into a mold-fixed side 503 and a mold-moving side 502. When the mold-moving side 502 is covered on the mold-fixed side 503, the material may be filled in the mold from the injection port 501 to form the multi-lens frame 180. Moreover, a part of the signal transmission elements 160 may be embedded in the multi-lens frame 180 to make the signal transmission elements 160 fixed in position when the multi-lens frame 180 is formed, which may minimize the overall size of the optical module.

Therefore, in an embodiment as shown in FIG. 15, the multi-lens frame 180 surrounding the signal transmission elements 160 may have an outer surface 184, a first inner surface 186, and second inner surface 188. The outer surface 184 extends from an edge of the circuit substrate 120, and has a tilted angle α with a central normal line of the sensing surface 1441. α is a value between 1° to 30°. The first inner surface 186 is an inner surface of the light channel 182. The first inner surface 186 has a tilted angle β with a central normal line of the sensing surface 1441. β is a value between 1° to 45°. The second inner surface 188 extends from the top surface of the circuit substrate 120 to the light channel 182, and has a tilted angle γ with a central normal line of the sensing surface 1441. γ is a value between 1° to 3°. With the positions of the tilted angle α, β, and γ, inferior quality of the multi-lens frame 180 may be prevented when the mold-moving side 502 is detached from the mold-fixed side 503, thus minimizing the chances for the situations like poor release features and molding flash.

Specifically, in an embodiment, as shown in FIG. 12 to FIG. 13, the multi-lens frame 180 may initially be formed partially, as in FIG. 12. After the signal transmission elements 160 are embedded in the multi-lens frame 180, the multi-lens frame 180 may thus be formed integrally. This makes the signal transmission elements 160 fixed in position when the multi-lens frame 180 is formed, which may minimize the overall size of the optical module.

As shown in FIG. 13, for the multi-lens frame 180 surrounding the signal transmission elements 160, under the condition that the multi-lens frame 180 is formed partially to embed a part of the signal transmission elements 160, the finally-formed multi-lens frame 180 may have an outer surface 184, a first inner surface 186, and second inner surface 188. The outer surface 184 extends from an edge of the circuit substrate 120, and has a tilted angle α with a central normal line of the sensing surface 1441. α is a value between 1° to 30°. The first inner surface 186 is an inner surface of the light channel 182. The first inner surface 186 has a tilted angle β with a central normal line of the sensing surface 1441. β is a value between 1° to 45°. The second inner surface 188 extends from the image sensor elements 140 to the light channel 182, and has a tilted angle γ with a central normal line of the sensing surface 1441. γ is a value between 1° to 3°. With the positions of the tilted angle α, β, and γ, inferior quality of the multi-lens frame 180 may be prevented when the mold-moving side 502 is detached from the mold-fixed side 503, thus minimizing the chances for the situations like poor release features and molding flash.

In another embodiment, as shown in FIG. 15 and FIG. 16, under the condition that the multi-lens frame 180 is formed directly to embed a part of the signal transmission elements 160, the finally-formed multi-lens frame 180 may have an outer surface 184, a first inner surface 186, and a second inner surface 188. The outer surface 184 extends from an edge of the circuit substrate 120, and has a tilted angle α with a central normal line of the sensing surface 1441. α is a value between 1° to 30°. The first inner surface 186 is an inner surface of the light channel 182. The first inner surface 186 has a tilted angle β with a central normal line of the sensing surface 1441. β is a value between 1° to 45°. With the positions of the tilted angle α and β, inferior quality of the multi-lens frame 180 may be prevented when the mold-moving side 502 is detached from the mold-fixed side 503, thus minimizing the chances for the situations like poor release features and molding flash.

In addition, in another embodiment, the multi-lens frame 180 may also be manufactured integrally by 3D printing. The tilted angle α, β, and γ may be formed according to demands. For instance, the tilted angle α, β, and γ may be used to improve structural intensity and minimize stray light, etc.

Each of the fixed-focus lens assemblies 230 may have at least two lenses 2401 with refractive power, be disposed on the lens base 220, and be positioned in the accommodating hole 2201. The image planes of each of the fixed-focus lens assemblies 230 may be disposed on the sensing surface 1441. An optical axis of each of the fixed-focus lens assemblies 230 may overlap the central normal line of the sensing surface 1441 in such a way that light is able to pass through each of the fixed-focus lens assemblies 230 in the accommodating hole 2201, pass through the light channel 182, and be emitted to the sensing surface 1441 to ensure image quality. In addition, PhiB denotes the maximum diameter of the image side surface of the lens nearest to the image plane in each of the fixed-focus lens assemblies 230. PhiA, also called the optical exit pupil, denotes a maximum effective diameter of the image side surface of the lens nearest to the image plane (image space) in each of the fixed-focus lens assemblies 230.

The fixed-focus lens assembly 230 further satisfies the following conditions: 1.0≤f/HEP≤10.0; 0 deg<HAF≤150 deg; 0 mm<PhiD≤18 mm; 0<PhiA/PhiD≤0.99; and 0≤2(ARE/HEP)≤2.0;

Specifically, f is the focal length of the fixed-focus lens assembly 230. HEP is the entrance pupil diameter of the fixed-focus lens assembly 230.

PhiA is the maximum effective diameter of the fixed-focus lens assembly 230 nearest to a lens surface of the image plane. ARE is the arc length along an outline of the lens surface, starting from an intersection point of any lens surface of any lens and the optical axis in the fixed-focus lens assembly 230, and ending at a point with a vertical height which is a distance from the optical axis to half the entrance pupil diameter.

In an embodiment, as shown in FIG. 3 to FIG. 6, the lens base 220 may include the lens barrel 222 and lens holder 224. The lens barrel 222 may have an upper hole 2221 which passes through two ends of the lens barrel 222, and the lens holder 224 may have a lower hole 2241 which passes through two ends of the lens holder 224 with a predetermined wall thickness TH1. PhiD denotes the maximum value of a minimum side length of an outer periphery of the lens holder 224 perpendicular to the optical axis on the surface.

The lens barrel 222 may be disposed in the lens holder 224 and be positioned in the lower hole 2241 with a predetermined wall thickness TH2. PhiC is defined as the maximum diameter of the outer periphery perpendicular to the optical axis on the surface. This allows the upper hole 2221 and the lower hole 2241 to be connected to constitute the accommodating hole 2201. The lens holder 224 may be fixed on the multi-lens frame 180 in such a way that the image sensor element 140 is positioned in the lower hole 2241. The upper hole 2221 of the lens barrel 222 faces the sensing surface 1441 of the image sensor element 140. The fixed-focus lens assembly 230 are disposed in the lens barrel 222 and is positioned in the upper hole 2221. PhiD is the maximum value of a minimum side length of an outer periphery of the lens holder 224 perpendicular to the optical axis of fixed-focus lens assembly 230.

In an embodiment, the optical image capturing module 10 may further include at least one data transmission line 400 electrically connected to the circuit substrate 120 and transmits a plurality of sensing signals generated from each of the plurality of 140 image sensor elements.

Furthermore, as shown in FIG. 8 and FIG. 10, a single data transmission line 400 may be used to transmit a plurality of sensing signals generated from each of the plurality of image sensor elements 140 of a dual lens, three lenses, array, or multi-lens optical image capturing module 10.

In another embodiment, as shown in FIG. 9 and FIG. 11, a plurality of single data transmission lines 400 may separately be disposed to transmit a plurality of sensing signals generated from each of the plurality of image sensor elements 140 of a dual lens, three lenses, array, or multi-lens optical image capturing module 10.

In addition, in an embodiment, the plurality of image sensor elements 140 may sense a plurality of color images. Therefore, the optical image capturing module 10 in the present invention has the efficacy of filming colorful images and colorful videos. In another embodiment, at least one of the image sensor elements 140 may sense a plurality of black-and-white images and at least one of the image sensor elements 140 may sense a plurality of color images. Therefore, the optical image capturing module 10 in the present invention may sense a plurality of black-and-white images together with the image sensor elements 140 of the plurality of color images to acquire more image details and sensitivity needed for filming target objects. This allows the generated images or videos to have higher quality.

In an embodiment, as shown in FIG. 3 to FIG. 7 and FIG. 17 to FIG. 21, the optical image capturing module 10 may further include IR-cut filters 300. The IR-cut filter 300 may be disposed in the lens base 220, located in the accommodating hole 2201, and positioned on the image sensor element 140 to filter out infrared ray. This may prevent image quality of the sensing surface 1441 of the image sensor elements 140 from being affected by the infrared ray. In an embodiment, as shown in FIG. 5, the IR-cut filter 300 may be disposed on the lens barrel 222 and the lens holder 224 and be positioned on the image sensor element 140.

In an embodiment, as shown in FIG. 6, the lens base 220 may include a filter holder 226. The filter holder 226 may have a filter hole 2261. The IR-cut filter 300 may be disposed in the filter holder 226 and be positioned in the filter hole 2261, and the filter holder 226 may correspond to positions of the plurality of light channels 182 and be disposed on the multi-lens frame 180 in such a way that the IR-cut filter 300 is positioned on the image sensor element 40 to filter out the infrared ray. This may prevent image quality of the sensing surface 1441 of the image sensor elements 140 from being affected by the infrared ray.

Therefore, under the condition that the lens base 220 includes a filter holder 226, the lens barrel 222 has an upper hole 2221 which passes through two ends of the lens barrel 222, and the lens holder 224 has a lower hole 2241 which passes through two ends of the lens holder 224, the lens barrel 222 may be disposed in the lens holder 224 and be positioned in the lower hole 2241. The lens holder 224 may be fixed on the filter holder 226. The lower hole 2241, the upper hole 2221, and the filter hole 2261 are connected to constitute the accommodating hole 2201 in such a way that the image sensor element 140 is positioned in the filter hole 2261. The upper hole 2221 of the lens barrel 222 may face the sensing surface 1441 of the image sensor element 140. The fixed-focus lens assembly 230 may be disposed may be disposed in the lens barrel 222 and positioned in the upper hole 2221 in such a way that the IR-cut filter 300 is positioned on the image sensor elements 140 to filter out the infrared ray entering the fixed-focus lens assembly 230. This may prevent image quality of the sensing surface 1441 of the image sensor elements 140 from being affected by the infrared ray.

In an embodiment, the present invention may be duel lenses of the optical image capturing module 10. Therefore, the plurality of fixed-focus lens assemblies 230 may include a first lens assembly and a second lens assembly. A field of view (FOV) of the second lens assembly may be larger than that of the first lens assembly 2411, and the field of view (FOV) of the second lens assembly may be larger than 46°. Therefore, the second lens assembly may be a wide-angle lens assembly.

Specifically, the plurality of fixed-focus lens assemblies 230 may include a first lens assembly and a second lens assembly, and the focal length of the first lens assembly is larger than that of the second lens assembly. If a traditional photo in the size of 35 mm (The field of view is 46°) is regarded as a basis, the focal length may be 50 mm. When the focal length of the first lens assembly is larger than 50 mm, the first lens assembly may be a long focal lens assembly. In a preferred embodiment, a CMOS sensor (with a field of view of 70°) with the diagonal of 4.6 mm is regarded as a basis, the focal length is approximately 3.28 mm. When the focal length of the first lens assembly is larger than 3.28 mm, the first lens assembly may be a long focal lens assembly.

In an embodiment, the present invention may be a three-lens optical image capturing module 10. Thus, the optical image capturing module 10 may have at least three fixed-focus lens assemblies 230 which may include a first lens assembly, a second lens assembly, and a third lens assembly. The plurality of fixed-focus assemblies 230 may include the first lens assembly, the second lens assembly, and the third lens assembly. The field of view (FOV) of the second lens assembly may be larger than that of the first lens assembly, and the field of view (FOV) of the second lens assembly may be larger than 46°.

The image sensor elements 140 corresponding to the third lens assembly may sense a plurality of color images or a plurality of black and white images according to requirements.

In an embodiment, the present invention may be a three-lens optical image capturing module 10. Thus, the optical image capturing module 10 may have at least three fixed-focus lens assemblies 230 which may include a first lens assembly, a second lens assembly, and a third lens assembly. The plurality of fixed-focus assemblies 230 may include the first lens assembly, the second lens assembly, and the third lens assembly. Moreover, the focal length of the first lens assembly is larger than that of the second lens assembly. Each of plurality of the image sensor elements 140 correspondingly receiving lights from the first lens assembly and the second lens assembly senses a plurality of color images. The image sensor elements 140 corresponding to the third lens assembly may sense a plurality of color images or a plurality of black and white images according to requirements.

Furthermore, in the optical image capturing module 10 provided by the present disclosure, when the surface of the lens is a convex surface, the surface of the lens adjacent to the optical axis is convex in principle. When the surface of the lens is a concave surface, the surface of the lens adjacent to the optical axis is concave in principle.

The image plane of the optical image capturing module 10 in the present application may be a plane or a curved surface depending requirements. When the image plane is a curved surface such as a spherical surface with a curvature radius, the incident angle necessary for focusing light on the image plane may be reduced.

The Second Optical Embodiment

As shown in FIG. 21, the fixed-focus lens assembly 230 may include seven lenses 2401 with refractive power, which are a first lens 2411, a second lens 2421, a third lens 2431, a four lens 2441, a fifth lens 2451, a sixth lens 2461, and a seventh lens 2471 sequentially displayed from an object side surface to an image side surface. The fixed-focus lens assembly 230 satisfies the following condition: 0.1≤InTL/HOS≤0.95. Specifically, HOS is the distance on the optical axis from an object side surface of the first lens 2411 to the image plane; InTL is the distance on the optical axis from an object side surface of the first lens 2411 to an image side surface of the seventh lens 2471.

Please refer to FIG. 24 and FIG. 25. FIG. 24 is a schematic diagram of the optical image capturing module according to the second optical embodiment of the present invention. FIG. 25 is a curve diagram of spherical aberration, astigmatism, and optical distortion of the optical image capturing module sequentially displayed from left to right according to the second optical embodiment of the present invention, As shown in FIG. 24, the optical image capturing module includes a first lens 2411, a second lens 2421, a third lens 2431, an aperture 250, a four lens 2441, a fifth lens 2451, a sixth lens 2461, a seventh lens 2471, an IR-cut filter 300, an image plane 600, and image sensor elements 140 sequentially displayed from an object side surface to an image side surface.

The first lens 2411 has negative refractive power and is made of a glass material. The object side surface 24112 thereof is a convex surface and the image side surface 24114 thereof is a concave surface.

The second lens 2421 has negative refractive power and is made of a glass material. The object side surface thereof 24212 is a concave surface and the image side surface thereof 24214 is a convex surface.

The third lens 2431 has positive refractive power and is made of a glass material. The object side surface 24312 thereof is a convex surface and the image side surface 24314 thereof is a convex surface.

The fourth lens 2441 has positive refractive power and is made of a glass material. The object side surface 24412 thereof is a convex surface and the image side surface 24414 thereof is a convex surface.

The fifth lens 2451 has positive refractive power and is made of a glass material. The object side surface 24512 thereof is a convex surface and the image side surface 24514 thereof is a convex surface.

The sixth lens 2461 has negative refractive power and is made of a glass material. The object side surface 24612 thereof is a concave surface and the image side surface 24614 thereof is a concave surface. Therefore, it may be effective to adjust the angle at which each field of view is incident on the sixth lens 2461 to improve the aberration.

The seventh lens 2471 has positive refractive power and is made of a glass material. The object side surface 24712 thereof is a convex surface and the image side surface 24714 thereof is a convex surface. Therefore, it is advantageous for the lens to reduce the back focal length to maintain minimization.

The IR-cut filter 300 is made of glass and is disposed between the seventh lens 2471 and the image plane 600, which does not affect the focal length of the optical image capturing module.
